Compatibility Issue with Pydantic V2

[AnasLahmar]

I am encountering a compatibility issue between langchain-redis and Pydantic V2. When using langchain-redis with Pydantic V2, I receive the following warning:

UserWarning: Mixing V1 models and V2 models (or constructs, like TypeAdapter) is not supported. Please upgrade IndexSchema to V2.

This suggests that langchain-redis is still using Pydantic V1 models internally, even though it depends on Pydantic V2.

@AnasLahmar We are doing a release soon to address some of this!
